The Duke's removal from the final remnants of monarchical duties has not only altered his path - it's creating waves through his family too.
The former spouse has now surrendered her ducal status and will simply be known as Sarah Ferguson.
For Sarah, sixty-six, the change will be the most apparent.
For all these years, she has maintained the honorary royal post-marital designation Sarah, York Duchess. Currently, she reverts to her maiden name of Ferguson.
"She has lost a certain prestige over this," noted one royal commentator. "She definitely utilizes the title – including her Twitter bio is @TheDuchessSarah."
But the loss of her title may affect her much less than the controversy she's facing separately about her own connections to Jeffrey Epstein.
Recently, multiple organizations dropped her as ambassador after correspondence from 2011 showed that she called Epstein her "supreme friend" and appeared to express regret for her public criticism of him.
Separate from her philanthropy, Ferguson also has multiple commercial enterprises.
And these ventures, are more likely to be impacted by the Epstein controversy than any change in title, notes one royal commentator.
But Ferguson has been a remarkable endure in royal circles. She's kept bouncing back.
"She's the ultimate survivor and master of reinvention," said one royal author.
For the couple's offspring, Beatrice, thirty-seven, and Eugenie, thirty-five, there's no official alteration.
They will still be known as princesses, which they have been granted since birth.
There is also no modification to the line of succession.
The prince stays eighth position to the throne, succeeded by his daughters Beatrice and Eugenie, in ninth and twelfth position in that order.
But in reality their positions are "distant" and will likely become even more remote as time goes on.
The princesses are also currently non-official royals, and while they occasionally take on roles – Princess Eugenie was recently named as a mentor for the King's Foundation program – experts also suggest they "can't see a world" in which they would step up into official responsibilities.
"As far as Beatrice and Eugenie are concerned, I think there's an understanding of the fact that this controversy doesn't involve them, and it's not fair for it to affect them directly in the independent lives they are carving out for themselves," says one monarchy analyst.
"The princesses are most unfortunate victims, they've had to endure quietly and have been dignified in their reserve," states another monarchy writer.
In the end, there appears to be minimal uncertainty that the individual who will be most affected by these developments will be the Duke himself.
For a man who always liked the trappings of royalty, the pomp and the pageantry, the relinquishment of his honors is profoundly embarrassing.
Therefore lacking those, on a personal level, will significantly count.
